Notes:

1. Exceeding the absolute maximum rating may damage the device.

2. The device is not guaranteed to function outside its operating rating.

3. Devices are ESD sensitive. Handling precautions recommended.

4. PD(max) = TJ(max) – TA) / θJA, where θJA depends upon the pointed circuit board layout. See “Applications Information.”

5. Output voltage temperature coefficient is defined as the ∆VOUT(worst case) / (TJ(max) – TJ(min)) where TJ(max) is +125°C and TJ(min) is 0°C.

6. VDO = VIN – VOUT when VOUT decreases to 99% of its nominal output voltage with VIN = VOUT + 1V.

7. IGND is the quiescent current. IIN = IGND + IOUT.

8. VEN ≤ 0.8V and VIN ≤ 8V, VOUT = 0.
